I.     INTRODUCTORY  STATEMENT 

The  study  of  the  TJredinales  of  California  began  with  the  pioneer 
work  of  Dr.  H.  W.  Harkness  and  Justian  P.  Moore,  who  in  1880 
published  a  Catalogue  of  Pacific  Coast  Fungi,  which  enumerates  fifty- 
five  species  belonging  to  this  group.  Unfortunately  this  list  does  not 
give  the  specific  names  of  a  large  number  of  the  host  plants  referred 
to  and  also  the  localities  are  often  very  indefinite,  which  makes  it  diffi- 
cult to  correlate  this  list  with  the  work  of  subsequent  collectors.  Some- 
what later  Dr.  Harkness,  either  in  conjunction  with  M.  C.  Cooke  and 
J.  B.  Ellis,  or  independently,  published  in  Grevillea  and  in  the  Bulle- 
tin of  the  California  Academy  of  Sciences  a  number  of  new  species 
including  many  Uredinales.  The  extensive  collections  of  Pacific  Coast 
fungi  which  Dr.  Harkness  had  presented  to  the  California  Academy 
of  Sciences  before  his  death  were  destroyed  in  the  great  fire  of  1906, 
with  the  exception  of  the  types  of  new  species  discovered  by  him, 
which  fortunately  were  preserved  through  the  foresight  of  Miss  Alice 
Eastwood,  the  present  Curator  of  the  Herbarium.

In  1882  Mr.  E.  W.  D.  Holway  began  work  on  the  rust  flora  of 
California  by  an  extended  exploration  of  King's  River  Canon  and 
vicinity,  which  brought  to  light  a  large  number  of  species,  some  of 
which  were  published  as  new  by  Dietel  and  Holway,  especially  in 
Erythea  and  Hedivigia.  With  the  aid  of  Mr.  Holway  this  work  was 
continued  by  the  writer,  and  collections  were  made  in  the  region  about 
San  Francisco  Bay  (1893  and  later),  Shasta  and  Siskyou  counties 
(1894),  Tuolumne  and  Calaveras  counties  (1895),  Lake  Tahoe  (1897), 
and  Mendocino  and  Humboldt  counties  (1896  and  1899).  Contempo- 
raneously and  in  the  succeeding  years  a  large  number  of  collectors 
did  work  in  other  regions.  Of  these  especial  mention  should  be  made 
of  A.  J.  McClatchie  (Pasadena),  S.  B.  Parish  (San  Bernardino), 
J.  Burtt  Davy  (Berkeley),  W.  R.  Dudley,  and  C.  H.  Thompson  (Stan- 
ford University).  In  more  recent  years  extensive  collections  have 
been  made  by  Ellsworth  Bethel,  Carl  T.  Baker,  David  Griffiths,  E.  E. 
Heller,  Dr.  Meinicke  of  the  Federal  Forest  Service,  and  Professor 
Home  of  the  Agricultural  Experiment  Station  of  the  University  of 
California. 


II.     THE  NEED  OF  EXPERIMENTAL  CULTURE  WORK 

Although  much  more  extended  collections  and  critical  studies  in 
both  field  and  laboratory  must  be  made  before  our  knowledge  of  the 
California  representatives  of  this  group  of  fungi  can  be  considered 
either  exact  or  complete,  it  is  believed  that  an  attempt  to  summarize 
the  information  now  available  will  be  of  assistance  to  those  working 
on  the  rust  flora  of  the  state  and  will  give  at  least  an  approximate 
idea  of  its  extent  and  content.  The  need  of  systematic  culture  experi- 
ments designed  to  establish  with  certainty  the  life  histories  of  those 
species  which  are  known  to  be  heteroecious  is  a  pressing  one.  The 
results  obtained  in  other  regions  of  the  United  States,  especially 
by  Arthur  and  his  collaborators  at  Purdue  University,  suggest 
the  species  of  host  plants  probably  concerned  in  the  life  histories  of 
many  of  the  Pacific  Coast  species;  but  the  differences  in  the  climatic 
conditions  of  the  two  regions  and  of  the  species  of  host  plants  found 
in  them  make  it  extremely  desirable  to  confirm  these  suggestions  by 
actual  experiments.  It  is  to  be  regretted  that  owing  largely  to  the 
lack  of  such  data  it  has  been  found  necessary  to  include  in  the  list 
here  presented  a  considerable  number  of  form  species,  that  is,  aecial 
and  uredineal  forms  not  definitely  correlated  with  the  mature  forms 


Blasdale:  Uredinales  of  California  103 

necessary  for  their  identification.  Apparently  an  unusually  large 
number  of  Pacific  Coast  forms  winter  over,  by  means  of  uredineal 
spores,  and  produce  telia  only  occasionally  and  in  very  small  amounts 
or  fail  entirely  to  do  so. 

Culture  experiments  are  also  greatly  needed  for  the  purpose  of 
ascertaining  the  specific  identity  of  many  of  those  species  which 
develop  on  closely  related  host  plants,  such,  for  instance,  as  the  forms 
of  Puccinia  which  are  found  on  the  different  genera  of  the  Onagraceae 
and  Compositae.  Such  experiments  in  other  regions  have  shown  great 
variability  as  to  the  closeness  of  the  adaptation  between  the  rust 
and  its  host.  In  some  instances,  as  illustrated  by  the  classical  work 
of  Eriksson  and  Hennings  with  the  grain  rusts,  this  relation  is  an 
extremely  narrow  one  and  it  becomes  clearly  necessary  to  recognize 
species  or  subspecies  based  upon  purely  physiological  distinctions. 
It  has  been  shown  by  Bethel,  on  the  other  hand,  that  certain  species, 
such  as  Puccinia  subnitens  and  P.  stipae,  produce  their  aecia  on  hosts 
belonging  to  genera  representing  widely  different  natural  families, 
and  it  is  not  improbable  that  too  much  emphasis  has  been  placed  upon 
the  host  plant  as  a  criterion  in  ascertaining  the  specific  limitations  of 
the  rusts. 


III.  PLAN  OF  THE  PRESENT  PAPER 

As  one  of  the  chief  objects  of  the  present  publication  is  to  assist 
collectors  in  naming  new  collections  and  to  tabulate  all  the  known 
forms  and  their  accompanying  host  plants,  the  different  genera,  which 
can  usually  be  readily  recognized  if  the  mature  form  is  at  hand,  have 
been  arranged  alphabetically,  and  where  a  large  number  of  species 
are  represented  those  species  which  occur  on  host  plants  belonging  to 
the  same  natural  family  have  been  grouped  together  and  the  groups 
arranged  according  to  the  sequence  of  families  found  in  Jepson's 
Flora  of  Middle  Western  California. 

The  references  cited  are  designed  merely  to  identify  with  certainty 
the  form  referred  to  and  to  indicate  where  a  description  of  it  can  be 
found.  Only  those  synonyms  have  been  given  which  are  necessary  to 
show  where  certain  species,  whose  validity  is  not  accepted,  belong  in 
the  list. 

The  data  represented  by  the  list  is  based  almost  wholly  upon  speci- 
mens in  the  herbarium  of  the  writer,  and  the  name  of  the  collector 
of  each  specimen  cited  is  given  in  parenthesis  except  where  the  col- 
lection is  that  of  the  writer,  in  which  case  it  is  omitted.

IV.     ACKNOWLEDGMENTS 

The  completeness  of  the  survey  of  the  rust  flora  of  California  here 
presented  is  in  a  large  measure  due  to  the  assistance  of  the  collectors 
whose  names  have  been  cited,  who  have  furnished  specimens  or  have 
given  additional  data  regarding  them.  Especial  obligations  are  due 
Mr.  Ellsworth  Bethel  for  a  large  amount  of  information  regarding  the 
heteroecious  species,  and  for  extended  collections  of  grass  and  sedge 
inhabiting  species  from  the  southern  part  of  the  state  both  of  which  are 
poorly  represented  in  most  of  the  collections  which  have  been  made 
up  to  the  present  time.  I  desire  also  to  express  my  thanks  to  Pro- 
fessor J.  C.  Arthur,  who  read  over  the  entire  list  of  species  here 
presented  and  made  many  valuable  suggestions.  It  will  also  be 
obvious  that  much  help  has  been  derived  from  such  portions  of 
Arthur's  arrangement  of  the  North  American  species  of  Uredinales 
(North  American  Flora,  vol.  7)  as  have  been  published,  of  the  critical 
work  of  Holway  in  that  portion  of  his  North-  American  Uredineae 
which  has  been  published,  and  Jackson's  Uredinales  of  Oregon,  pub- 
lished in  the  Memoirs  of  the  Brooklyn  Botanic  Garden. 


V.  GENERAL  FEATURES  OF  THE  UREDINALES 

The  Uredinales  represent  a  group  of  fungi  whose  vegetative  parts 
consist  of  a  much  branched  and  septate  mycelium,  which  develops  in 
the  leaves,  branches,  and  fruits  of  certain  seed  producing  plants  and 
ferns  and  abstracts  nourishment  from  the  cells  of  the  surrounding 
tissues  by  means  of  haustoria.  The  reproductive  parts  are  represented 
by  five  different  types  of  spores,  one  or  more  of  which  are  frequently 
lacking  and  which  differ  greatly  as  to  form  and  size  as  well  in  the 
mode  of  production  and  germination.  The  different  spore  forms  are 
the  following: 

Spermatia,  designated  by  the  symbol  0,  are  produced  in  sub- 
globose  or  flask-shaped  spermogonia  and  are  minute  hyaline  bodies, 
which  can  be  made  to  germinate  but  do  not  appear  to  perform  any 
important  function  in  the  life  history.  They  usually  appear  with 
or  slightly  before  the  aecia. 

Aeciospores,  designated  by  the  symbol  I,  are  produced  in  cup- 
shaped  or  cylindrical  aecia,  which  have  a  more  or  less  well  developed 
peridium,  or  in  masses,  frequently  surrounded  by  paraphyses,  in 
which  a  peridium  is  lacking.  They  are  always  one-celled  and  are 
formed  by  the  successive  abstriction  of  the  ends  of  closely  packed 


Blasdale:  Uredinales  of  California  105 

hyphae.  They  have  a  hyaline  epispore  and  a  number  of  germ  pores 
but  rapidly  lose  their  ability  to  germinate. 

Urediniospores  designated  by  the  symbol  II,  are  usually  produced 
in  subepidermal  sori  and  ultimately  burst  through  the  epidermis  as 
light  brown  or  yellow  pulverulent  masses.  They  are  produced  singly 
at  the  ends  of  hyphae,  are  always  one-celled,  either  globose,  elliptical 
or  pyriform,  possess  several  germ  pores  and  are  either  echinulate  or 
tuberculate. 

Teliospores,  designated  by  the  symbol  III,  are  formed  like  the 
urediniospores,  but  sometimes  appear  singly,  either  in  or  on  the  tissues 
of  the  host.  They  usually  possess  a  definite  pedicel  and  may  be 
fascicled  or  compacted  into  a  crust  or  a  cylindrical  column.  Each 
spore  may  consist  of  a  single  cell  or  of  as  many  as  twenty  cells; 
each  cell  usually  possesses  a  single  germ  pore.  They  possess  a  thick 
epispore,  which  is  dark  brown  or  black  in  color.  On  germination 
they  produce  a  thick  promycelial  tube,  which  ultimately  produces  four 
cells,  each  of  which  develops  a  single  basidia  and  sporidium.  "When 
the  sporidia  germinate  they  produce  short  tubes  which  are  able  to 
penetrate  the  tissues  of  the  proper  host  plant.  The  formation  of 
basidia  is  one  of  the  most  distinguishing  characteristics  of  the  group. 

Many  species  show  well  characterized  alternation  of  generations 
on  host  plants  belonging  to  the  same  species  (autoecious)  or  on  host 
plants  belonging  to  different  species  (heteroecious).

on  Q.  dumosa  Nutt.,  Pasadena  (McClatchie). 

There  seems  to  be  no  essential  difference  between  the  eastern  and 
western  forms  of  this  species,  although  culture  experiments  are  needed 
to  prove  this  conclusively.  Meinicke  (Phytopathology,  vol.  6,  p.  225, 
1916)  has  shown  that  aecial  spores  from  Pinus  radiata  could  be  made 
to  reproduce  aecia  on  the  same  host  without  an  intervening  stage; 
also  that  the  fungus  winters  over  in  the  uredinial  stage  on  the  leaves 
of  Quercus  agrifolia. 

ERIOSPORANGIUM  (BERTEBO)  LEV.

The  aecial  stage  is  probably  Coleosporium  Baccharidis  Cooke 
(Grevillea,  vol.  9,  p.  7,  1880),  which  produces  galls  often  of  large  size 
on  the  branches  of  Bacchari-s  consanguinea  Greene  and  B.  pilularis 
DC,  similar  to  those  of  the  bark-inhabiting  species  of  Peridermium.

Uredinia  and  telia  occur  on  the  leaves  of  the  same  hosts,  but  as  the 
sori  are  small  they  are  easily  overlooked.  The  genetic  connection 
between  the  two  forms  has  not  been  proven;  but  the  frequency  with 
which  they  are  associated  makes  it  probable  that  they  are  so  related. 
It  is  common  throughout  the  bay  region  and  in  southern  California.

The  genetic  connection  between  the  two  stages  was  first  established 
by  Arthur  (Mycologia,  vol.  1,  p.  252,  1909,  vol.  4,  p.  57,  1912),  who 
succeeded  in  growing  aecia  on  Crategus  PringUi  Sarg.  from  telia 
obtained  from  Corvallis,  Oregon.  From  the  latter  state  it  is  reported 
to  be  a  rather  serious  pest  by  O'Gara  (Science,  vol.  39,  p.  60,  1914), 
and  by  Jackson  (Phytopathology,  vol.  4,  pp.  41,  261),  attacking 
especially  pears,  quinces,  and  certain  varieties  of  apples.

with  pycnia,  the  spores  of  which  germinate  like  teliospores.  It  is  not 
distinguishable  morphologically  from  the  aecial  stage  of  the  genus 
Gymnoconia,  but  the  aecial  spores  of  the  genus  last  named  germinate 
like  true  aecia  spores,  and  there  is  an  alternate  stage  not  distinguish- 
able from  the  telia  of  the  genus  Puccinia.

its  similarity  to  the  preceding  species  makes  it  probable  that  it  is  also 
a  short-cycle  form.  It  appears  very  early  in  the  spring  and  produces 
hypertrophy  and  ultimate  death  of  the  affected  shoots.

Cruz  (Griffiths)  ;  on  8.  speciosa,  Victorville  and  Granite  Mountain 
(Bethel)  ;  on  8.  sp.,  Mill  Valley  and  San  Diego  (Bethel)  ;  on  Oryzopsis 
hymenoides  Eicker,  Victorville  (Bethel). 

The  connection  between  these  forms  has  been  established  by  Bethel 
by  repeated  cultures  with  both  telia  and  aecia,  the  first  being  made 
in  Colorado  in  1912.  His  numerous  collections  of  both  aecia  and  telia 
in  1916  and  1918  in  southern  California,  not  far  from  the  type  locality 
of  Roestelia  interveniens  establish  the  validity  of  the  combination 
given  above.  The  aecia  have  very  short  peridia,  split  almost  to  the 
base,  as  in  the  form  genus  Roestilia;  the  telia  form  sori  from  one  to 
three  inches  in  length,  especially  on  the  sheaths,  which  are  tardy  in 
rupturing.

This  species  is  more  closely  related  to  P.  Adenostegiae  Arth.  than 
to  P.  Anthirrhini  Diet,  and  Holw. ;  it  differs  from  the  latter  in  the 
characters  of  the  sori,  and  from  both  in  the  form  and  size  of  the  telio- 
spores. These  differences  are  shown  in  the  figures  given  below,  which 
represent  the  results  of  the  measurement  of  forty  mature  spores  of 
each  of  the  three  species.

ADDENDA 

The  following  represent  important  additions  to  the  foregoing  list 
the  data  for  which  were  received  too  late  for  inclusion  in  the  proper 
sequence. 

231.  Cronartium  occidentale  Hedgcock,  Bethel,  and  Hunt.    0,  I, 

II,  III 

Jour.  Agric.  Kesearch,  vol.  14,  p.  411,  1918. 

Aecial  stage  not  as  yet  reported  from  California  but  found  in 
Colorado,  Utah,  New  Mexico,  and  Arizona  on  species  of  Pinus  belong- 
ing to  the  piiion  group. 

Uredinia  and  telia  on  Ribes  tenuiflorum  Lindl.,  "abundant  along 
river  wash  near  Monrovia"  (Bethel).  It  was  first  reported  from  the 
same  locality  by  W.  M.  Phillipson. 

This  record  is  of  especial  interest  on  account  of  the  similarity  of 
the  uredinial  and  telial  stages  to  those  of  the  white  pine  blister  rust, 
the  aecial  stage  of  which  is  very  destructive  to  pines  of  the  five-leaved 
group.
